The present invention relates to a flooring decorative material and a method of applying the color change effect, and more particularly, to form a uniform printing layer including two pigments having a light reflection effect in the interior of the flooring decorative material and to change the angle of the printing layer. The present invention relates to a flooring material and a method of imparting the effect of changing the color of the same part to two or more colors according to the visual difference by varying it.

Conventionally, the surface layer 4 is transparently formed on the base material I (or the foam layer 2 is formed on the special glass fiber layer 5) as the first diagram in order to increase the appearance effect of the flooring material. A printing layer 3 formed by various printing methods on the surface layer 4 to be projected through the surface layer 4, a method of imparting a stereoscopic effect using a pigment having a light reflection effect, or a printing layer containing reflective ink The range of products that consumers can choose through the continuous development of products that can be seen or invisible according to the visual point by providing visual quality has been widened. It was not enough to meet new consumer needs.

Therefore, in the present invention, by using the effect according to the reflection angle of the pigment having a reflection effect by varying the angle of the printing layer containing the pigment having a reflection effect present in the lower surface layer in various ways, the color of the same site is two or more colors according to the visual difference The object of the present invention is to provide a flooring decorative material and a method of applying the same, which are manufactured to be changed to improve appearance effects.

Hereinafter, the manufacturing process and the effect of the present invention will be described in detail with reference to the accompanying drawings.

2 is a manufacturing process diagram schematically showing the manufacturing process of the present invention as a substrate is used as a special glass fiber (Glas Fiber), mineral paper (Mineral paper), etc. In the case of using a special glass fiber plastisol (plastisol) It is used by combining with, and the joining method is a known method such as knife coating, bar coating, reverse roll coating.

The substrate 10 released from the roll state was coated (11) with a 0.3 mm thick plastisol containing 53.7% resin, 23.7% DOP, 6.7% filler, 1.5% blowing agent, and the like. The apparatus 12 is gelled by heating at 150 ° C. ± 5 ° C. for 1 minute and then cooled in the cooling apparatus 13.

Printing apparatus capable of printing up to 5 degrees using ink containing 10-20% of foam inhibitors in suppressing ink and 1-5% of pearl pigment (MEARL®, specific gravity: 3.0) in reflective ink (14 After printing the printed layer (I) in the drying apparatus 15 by heating at 80 ℃ for 10 seconds and dried, by applying pressure in the embossing roll 16 of 180 ℃ ± 5 ℃ to transfer the pattern and then the cooling apparatus (17) Cool down to).

Subsequently, the transparent layer coating 18 was coated with a plastisol containing 71.4% of a high-transparent resin and 28.6% of DOP, and then gelled by heating at 160 ° C. ± 5 ° C. for 1 minute in a heating device 19, followed by cooling (20) and a printing device ( 21) after printing the printing layer (II), the surface layer coating (22) with a plastisol containing a resin stabilizer and the like, and the gelling and foaming layer was heated by a heater (23) at 200 ℃ ± 5 ℃ 30 seconds-3 minutes. After foaming, if necessary, mechanical embossing (24) and cooling in the cooling device (25), the finished product is wound in a winding roller (26). And when there exists a back layer, a back layer is formed by a well-known method.

The flowchart of the above-mentioned manufacturing process to understand more easily is as follows.

3 shows a cross-sectional configuration diagram of the floor covering of the present invention.

In the present invention, when the pigment is applied to the surface of the crystalline material (for example, mica) as the fourth degree, the reflection of light is reversed according to the visual difference. Depending on the light appears or disappears.

This can be explained by the phenomenon where the wavelength of the light reflected by the pigment applied to the surface of the crystalline material and the light reflected from the surface of the crystal overlap.

○ In the case of stronger light: 4nh cosr ± 1 / 2λ = mλ

○ In case of weak light: 2nh cosr ± 1 / 2λ = 2mλ

(n: refractive index, m: integer, λ: wavelength)

5 is a method of causing different colors to appear on the same site. As shown in FIG. 5, when the angles of the crystalline materials coated with pigments of different colors are changed, the colors at different angles appear strongly with respect to the same light source.

At this time, when the color body 1 and the color body 2 are overlapped, the color body of the same part changes with time.

FIG. 6 shows the application of the method. When the flooring material is manufactured as shown in FIG.

In more detail, the light reflected on the same light source A is reflected at different angles such as B, C, and D.

At this time, the difference in angle between the print layer (I) and the print layer (II) becomes very important. D appears far away from the observer, C appears near the observer, and B appears behind the observer.

Figure 7 shows the shape and cross-sectional view of the reflective pattern transfer roll, the shape of the transfer roll can be produced in the form (a), amorphous (b), focus (c), the effect of the color change is the cross-sectional angle of the transfer roll It depends on the ratio (h / a) and the value of a or h alone is related to the pattern density. At high densities, the EMBO pattern is inconspicuous and only gives the effect of color change. At low densities, the EMBO pattern is also visible. The cross-sectional angle (h / a) ratio is preferably 0.1-0.5, but may be used in combination with a constant ratio and a different ratio as necessary.

In addition, in the regular pattern such as (a), the color surface of the nearby and slightly separated areas can be seen by changing the h / a value on the entire surface of the upper material, and in the amorphous pattern such as (b), slightly different h By using the value / a, the effect is as if the surface is lit by sunlight.

In the case of the focus type as shown in (c), the necessary pattern can be obtained to stand out clearly at the required angle.

However, these three are not fixed but can be diversified by adjusting the range of h / a values or changing the print pattern as needed.
